Abstract

The citrus brown mite Eutetranychus orientalis (Klein), is known as one of the most significant pests in citrus growing areas worldwide. It has recently caused outbreaks in the Mediterranean region of Türkiye. This study aimed to determine the resistance levels of E. orientalis populations between 2020 and 2021 collected from 9 commercial citrus orchards in Adana province against 5 different acaricides, in order to determine whether the observed population outbreak was due to acaricide resistance. The resistance ratios were changed between 1.67 and 2.50, 1.00–2.53, 1.85–3.68, 1.30–2.65, and 1.93–3.13-fold for abamectin, etoxazole, fenbutatin oxide, pyridaben, and spirodiclofen, respectively. The enzyme activity levels of carboxylesterase, glutathione S-transferase, and cytochrome P450 monooxygenase ranged between 1.00 and 1.13, 1.02–1.52, and 0.94–1.72-fold, respectively. As a result of the resistance study carried out for the first time on this species in Türkiye, the resistance ratios were determined to be low for E. orientalis against acaricides. Although the current resistance rates were low, certain populations exhibited a noteworthy surge in enzyme activities when compared to the susceptible population. Based on these findings, it was concluded that by implementing an appropriate resistance management strategy using acaricides with different modes of action, it is possible to prevent potential resistance development and use these acaricides effectively on this spider mite species for many years through rotation.

从土耳其南部采集的柑橘园入侵蜘蛛螨 Eutetranychus orientalis(Acari: Tetranychidae)田间种群对杀螨剂的抗性水平较低
柑橘褐螨 Eutetranychus orientalis (Klein) 是全球柑橘种植区最主要的害虫之一。最近,它在土耳其地中海地区爆发。本研究旨在确定 2020 年至 2021 年期间从阿达纳省 9 个商业柑橘园收集的东方桉树种群对 5 种不同杀螨剂的抗性水平,以确定观察到的种群爆发是否是杀螨剂抗性所致。阿维菌素、乙螨唑、氧化芬布津、哒螨灵和螺螨酯的抗药性比率分别为 1.67-2.50 倍、1.00-2.53 倍、1.85-3.68 倍、1.30-2.65 倍和 1.93-3.13 倍。羧基酯酶、谷胱甘肽 S 转移酶和细胞色素 P450 单氧化酶的酶活性水平分别为 1.00-1.13 倍、1.02-1.52 倍和 0.94-1.72 倍。土耳其首次对该物种进行了抗药性研究,结果表明东方鳗鲡对杀螨剂的抗药性比率较低。虽然目前的抗药性比率较低,但与易感种群相比,某些种群的酶活性显著增加。根据这些发现得出的结论是,通过使用具有不同作用模式的杀螨剂来实施适当的抗药性管理策略,可以防止潜在的抗药性发展,并通过多年轮换对这种蜘蛛螨类有效地使用这些杀螨剂。

期刊介绍: The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
